M injectors on a 2.5?

[e8503]

Hi all, I recently discovered a cracked injector on my 2003 bmw z4, so I thought that I might as well get a little more power out of my engine and upgrade all 6. Does anyone know if injectors out of like an s54 would work?

You can’t just fit larger injectors & gain more power, I doubt the original ones are running at the top of their duty cycle.

sure not without a tune, more air, and better ignition, but that's all coming too. Regardless, after doing a little research I realized that aftermarket is probably the way to go, m injectors don't have a fast enough cc/min compared to more affordable aftermarket options to be a viable tuner option.
